An hour before the start of the NASCAR Sprint Cup Series finale at Homestead-Miami Speedway, the cars of three of the four championship drivers had yet to pass technical inspection. The No. 18 team of Kyle Busch was the only one on the grid, and NBC Sports Network said the other cars failed three different times.

Since that report, ESPN’s Bob Pockrass tweeted that the cars of championship contenders Carl Edwards, Joey Logano and Jimmie Johnson made it through tech. If the math is right here, that was their fourth attempt.

Of the four drivers remaining, the highest finisher in Sunday’s race will win the championship title. Under NASCAR’s new knockout Chase format, Busch won the 2015 championship after missing 11 races due to injury.

Update, 3:28 p.m. ET: Well, scratch that! Jimmie Johnson had to drop to the back of the field for the start of the race for unapproved body modifications found after tech, according to a tweet from the Associated Press’ Jenna Fryer.
